3. Privileges.

In versions up to and including 0.99.6, it was necessary to run
Wireshark with elevated privileges in order to be able to capture
traffic. With version 0.99.7, all function calls that require elevated
privileges have been moved out of the GUI to dumpcap.

WIRESHARK CONTAINS OVER TWO MILLION LINES OF SOURCE CODE. DO NOT RUN
THEM AS ROOT.

That's not a Wireshark bug; neither Xquartz nor xhost are part of Wireshark.

You'll need to figure out what's wrong with X11 on your machine.
